Good sideboard tech against a lot of tricks in this block, including Mogg Fanatic, Auratog, Rootwalla and even enchantments like Goblin Bombardment. Wrecks Morphling, etc... Really in the end this card wrecks a surprisingly high number of tactics and combat tricks. Great for decks with big creatures that just don't need those tricks. Ruins flowstone too.

Of course, you could always still do all the combat abilities on your main phase...

It has some niche uses. The most important effect of this card I can think of is its nullification of protection lands like Maze of Ith, Mystifying Maze and Kor Haven, since they can target only attacking creatures.

The WoTC R&D folk have said that it was never intended and in a sense was an oversight, but the main effect this has is to nullify all damage prevention and redirection that could happen during the combat.

I've never figured out how to properly use this card in a deck.

Keeps combat limited to combat.
